Smog Check FAQ

What is a Test Only Station?

Test-Only stations are licensed by the state only to perform tests on vehicles. They are prohibited from performing any repair services. Gross Polluters can also be certified at these stations.

Who requires a Smog Check?

The Department of Motor Vehicles renewal notice will indicate whether a Smog Check is required to re- register your vehicle. Most areas of the state require vehicles to have a Smog Check performed every two years, when being sold, and when being initially registered in California.

Do I really need a Smog Check?

Not all vehicles must get a Smog Check. Smog Check need depends on the type of vehicle, the model-year, and the area in which the vehicle is registered. Additionally, some vehicles only need a Smog Check when they are being sold or being registered in California after previously being registered in another state.

What is a STAR smog check?

If you received the DMV registration renewal paper saying “SMOG Certification Required at a STAR station”, you are at the right place. Premier Star Smog is a Star Certified Smog Check Station. STAR Smog Station means, DMV has chosen your car to be inspected at a smog station which is monitored closely by the BAR (Bureau of Automotive Repair) and must conform to high standards established by the Bureau of Automotive Repairs.

What is the difference between a regular smog station and a STAR smog station?

STAR smog stations will be able to issue a certificate of compliance to a vehicle passing a smog check when a motorist is referred by the DMV to such a station for vehicle registration renewal. A non “star” station may not issue a certificate to the motorist’s vehicle. They may however, test and issue certificates to vehicles not directed by the DMV to a “STAR” smog check station.

How much does a test only smog check cost? Does a test only center charge more?

Smog test only stations are not allowed to profit or perform any auto repairs, whether smog check related or not. In the past smog test only centers typically charged more for their smog inspection in order to cover their expenses. In today’s market however, with competition being so great, and the fact that there are plenty of test only directed vehicles to go around, the cost of the test only smog check has been dramatically reduced.

How can I help my vehicle pass Smog Check?
